300 hp? When are you swapping in an LS?
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
Sorry, forgot to mention I am building up the engine with an eventual goal of 300hp. I posted a list of mods in another thread, so I'll try to find it. I guess it's not completely ZFG but like it's just meant to be a fun car, bought it for $500 CAD to learn about cars. Also I don't know what FWIW means sorry. I also just had the idea of running one of those electric butterfly valves between a hoodpipe and a downpipe with a muffler for residential driving or if I see a cop lol.
Edit: found the list:
- 60 A/R intake, 63 A/R exhaust T3/T4 turbo (externally wategated using adapter plate)
- Ebay stainless header (with flange flipped and supported)
- 13mm rods from 90+ b230ft
- new piston rings
- new rod bearings
- replacing all gaskets/seals in the head.
- re lapping valves
- porting head ???
- 2.5" hoodpipe
- new spark plug wires
- electronic boost controller
- wideband gauge
- boost gauge
- upgraded injectors (low impedance brown-top equivalent)(setup using the guide forum)
- removal of stock air box for cone filter.
- possible ebay intercooler if I can find another $200 CAD
I think that's it but I'm probably missing something lol. Ill jut edit as I remember things.
It will be over 96dbz.
1. I ran the wastegate on my Evo external dump (though... not out the hood because I think it's ridiculous ESPECIALLY if you're trying to save money) this is mine actually lol
It sounded GREAT until WOT. It sounded like a McLaren Mercedes as the WG was flapping about... after that, it sounded like tractor. It was also WAY too loud. And that's with a turbo in the way.
2. I ran the Volvo with both "some" exhaust and "no" exhaust. While I generally like the tractor motor sound it makes, and with the "some" exhaust once you got onto the revs you could definitely hear the neat grpA sounds (regardless of how different the motor is) it was LOUD. Like... you won't be able to have a conversation loud. This was with no turbo.
3. I ran turbo and downpipe (15g) and it was quiet enough, but it sounded like a semi truck. Too whistley. I added a HF cat and a muffler (straight through) and exited out the side and it sounds quite good now... but it's definitely too quiet. I'll probably experiment with some other choices.
Toxicfab also makes that O2 housing in a hood dump. Cutting a hole in your hood to save money is like fighting for peace or screwing for virginity. You can run it down and have the same exact thing. But my real point is... it will be loud. Unless I'm missing something silly.
You also need a plan for water.
FTFY
That piece is nice! great work.
Well considering everyone's concern, I'm genuinely considering picking up one of those $50 Ebay butterfly valves and some how setting it up so I can choose between a muffled downpipe (not built all the way back) and a hoodpipe. The only problem is I cant seem to find a valve that switches between two pipes, they are all just open or closed (meaning I would need 2 to actually switch between exhaust options). Also I'd have to find a place to put the O2 sensor bung so that it works for either configuration. Anyone ever done anything similar?
Guys please understand that this is not for "street cred" its for saving money, that's it and that's all.
